Title: Coated optical fiber
Inventor: TAKAHASHI FUMIO
IPC: G02B6/44
Filed: 1988-12-28
Abstract: PURPOSE:To manufacture the coated optical fiber with easiness nearly equal to that of a tight type coated optical fiber while suppressing an increase in the external diameter of a coating, not to mention the protecting function of the optical fiber by forming part of the coating layer below the coating layer of the outermost part by using a high polymer material which changes into liquid with heat energy and/or light energy. CONSTITUTION:For example, three coating layers 13 - 15 are formed on the outer periphery of the optical fiber 12 and the intermediate coating layer 14 between the innermost coating layer 13 and outermost coating layer 15 is made of the high polymer material which changes into liquid. Then the intermediate coating layer 14 changes into the liquid in a short time at high temperature. Thus, the coating layer 14 of the coated optical fiber changes into the liquid, a gap is formed between the specific coating layers 13 and 15, so the coating structure changes from a tight type to a loose type. Consequently, the loose type coating structure which is small in external coating diameter is obtained while the protecting function of the optical fiber is secured, and the fiber can be manufacture with easiness nearly equal to that of the tight type.
